This application is a continuation of application Ser. No. 07/143,848 filed on Dec. 16, 1987 which is now abandoned.

TECHNICAL FIELD

The present invention relates to a method for producing an optically active cyclopropane carboxylic acid. More particularly, the present invention relates to a method for producing optically active cyclopropane carboxylic acid derivatives or their salts represented by the following formula (I): ##STR3## wherein X is as defined below, by asymmetric hydrolysis of cyclopropane carboxylic acid esters represented by the following formula (II): ##STR4## wherein X and R are as defined below, with microorganisms or esterases produced by the microorganisms.

BACKGROUND OF THE INVENTION

The cyclopropane carboxylic acids represented by the above formula (I) constitutes the acid moiety of a low toxic and rapidly acting insecticidal ester generally termed pyrethroid such as allethrin, permethrin, decamethrin, teffuluthrin, etc.

The cyclopropane carboxylic acids represented by the formula (I) contain two asymmetric carbon atoms at the 1-position and the 3-position and therefore have four diastereomers. Of these isomers, those having the absolute configurations of "1R, 3S" and "1R and 3R" are termed "(+)-cis isomer" and "(+)-trans isomer" (according to RS nomenclature), respectively, because the optical rotation of these isomers is (+) in a specific solvent and substitution groups of them are in a cis-form and a trans-form, respectively. And, the other two isomers having the absolute configurations of "1S, 3S" and "1S, 3R" are termed "(-)-cis isomer" and "(-)-trans isomer", respectively, because the optical rotation of these isomers is (-) in a specific solvent and substitution group of them are in a cis-form and a trans-form, respectively. Only the (+)-isomers have insecticidal activities as pyrethroid esters and the (-)-isomers have almost no insecticidal activities as pyrethroids.

The relative effects of the cis and the trans isomers vary according to the kinds of harmful insects to be killed and the type of effect.

It is possible to use the (+)-trans-pyrethroidal compound and (+)-cis- compound independently for different purposes. Accordingly, the production of (+)-cyclopropane carboxylic acids in effective manner is industrially important.

The presently known major method for production of (+)-isomers is organosynthetic optical resolution, but development of more economical methods for optical resolution is now desired for production of (+)-isomers because the organosynthetic optical resolution requires a relatively expensive optically active reagent or a complicated step. There are known methods for producing optically active (+)-trans acid by resolving cyclopropane carboxylates by asymmetric hydrolysis with a pig liver esterase (e.g., Schneider et al., Angewande chemie International Edition in English 23. 64 (1984)) or with a microbial esterase (Japanese Patent Publication (Kokai) No. 244295/1985).

However, the former method is industrially disadvantageous because of the expense and limited supply of the pig liver esterase. As for the latter method, it is reported that the trans-isomer of cyclopropane carboxylic acid ester is preferentially resolved by asymmetric hydrolysis but the method can not be industrially applied because the yield of (+)-trans-cyclopropane carboxylic acid is as low as 31 mg/100 ml culture medium, and the concentration of the substrate and the optical purity of the resulting (+)-trans cyclopropane carboxylic acid are low.

DISCLOSURE OF THE INVENTION

Under these circumstances, the inventors of this invention developed an industrially advantageous method for producing (+)-cyclopropane carboxylic acid (I). As a result, the inventors found that microorganisms belonging to the genera Rhodotorula, Rhodosporidium, Rhizomucor, Flammulina, Geotrichum, Aspergillus, Candida, Saccharomyces, Hansenula, Torulopsis, Rhodococcus, Penicillium, Dipodascus, Absidia, Streptomyces, Nocardia, Arthrobacter, Pseudomonas, Escherichia, Bacillus, Beauveria, Metschnikowia, Chromobacterium, Brevibacterium, Acinetobacter, Achromobacter, Kluyveromyces, Frateuria, Corynebacterium, Alcaligenes, Flavobacterium or Klebsiella, or an esterase produced by the above microorganisms specifically and preferentially hydrolyze (+)-cis-cyclopropane carboxylic acid esters represented by the formula (II): ##STR5## wherein X represents chlorine atom, bromine atom, methyl group or trifluoromethyl group and R represents C₁ -C₄ alkyl group C₁ -C₄ substituted by halogen atom, the configuration of the esters not being indicated by the formula, to produce optically active (+)-cis-cyclopropane carboxylic acid derivatives represented by the formula (III) or their salts: ##STR6## wherein X represents as above, R' represents hydrogen atom or metal ion, the configuration of the acid (I) not being indicated, and (-)-cis-cyclopropane carboxylic acid esters (II), and that the resulting (+)-cis-cyclopropane carboxylic acid derivatives or their salts are recoverable with high optical purity.

It was also found that, in the case of optically active cis-cyclopropane carboxylic acid esters represented by the formula (IV): ##STR7## wherein R represents an alkyl group containing 1-4 carbon atoms or an alkyl group containing 1-4 carbon atoms substituted by halogen atom, which does not indicate the configuration of the esters, optically active cis-cyclopropane carboxylic acid derivatives or its salts are produced with high optical purity by allowing the esters to react with microorganisms belonging to the genus Arthrobacter or Bacillus or esterases produced by these microorganisms to yield optically active (+)-cis-cyclopropane carboxylic acid and recovering it. Examples of microorganisms used for this purpose are Arthrobacter globiformis IFO-12958 and Bacillus sp. DC-1 (BP-FERM 1254).

and that (+)-trans-2,2- dimethyl-3(2,2-dichlorovinyl)cyclopropane carboxylic acid or its salts are prepared with high optical purity.

In particular, it was confirmed that when Bacillus sp.

The present invention provides a method for producing optically active (+)-cis-cyclopropane carboxylic acid derivatives or their salts which comprises allowing (±)-cis-cyclopropane carboxylic acid esters represented by following formula (II): ##STR9## wherein X represents chlorine atom, bromine atom, methyl group or trifluoromethyl group, and R represents C₁ -C₄ alkyl group or C₁ -C₄ alkyl group substituted by halogen atom, which does not indicate the configuration of the ester, to react with microorganisms belonging to the genera Rhodotorula, Rhodosporidium, Rhizomucor, Flammulina, Geotrichum, Aspergillus, Candida, Saccharomyces, Hansenula, Torulopsis, Rhodococcus, Penicillium, Dipodascus, Absidia, Streptomyces, Nocardia, Arthrobacter, Pseudomonas, Escherichia, Bacillus, Beauveria, Metschnikowia, Chromobacterium, Brevibacterium, Acinetobacter, Achromobacter, Kluyveromyces, Frateuria, Corynebacterium, Alcaligenes, Flavobacterium, or Klebsiella or the esterases derived from these microorganisms, thereby asymmetrically hydrolyzing, with specificity and preference, (+)-cis-cyclopropane carboxylic acid esters of the formula (II) above to give optically active (+)-cis-cyclopropane carboxylic acid or their salts represented by formula (III): ##STR10## wherein X represents as above and R' represent hydrogen atom or metal ion, which does not indicate the configuration, and (-)-cis-cyclopropane carboxylic acid esters of the formula (II), and recovering the resulting optically active (+)-cis-cyclopropane carboxylic acids or their salts of the formula (I).

This invention also provides a method for producing (+)-cis-cyclopropane carboxylic acid derivative or its salts represented by the formula (VI): ##STR11## wherein R' represents hydrogen atom or metal ion, which does not indicate the configuration, which comprises allowing (±) -cis-cyclopropane carboxylic acid ester represented by the formula (IV) ##STR12## wherein R represents C₁ -C₄ alkyl group or C₁ -C₄ alkyl group substituted by halogen atoms, which does not indicate the configuration, to react with microorganisms belonging to the genus Arthrobacter or Bacillus or esterase produced by the above microorganisms and then recovering the resulting (+)-cis-cyclopropane carboxylic acid derivative or its salt of formula (I).

This invention further provides a method for producing (+)-trans-2,2-dimethyl-3(2,2-dichlorovinyl)cyclopropane carboxylic acid or its salts which comprises allowing (±)-2,2-dimethyl-3(2,2-dichlorovinyl)cyclopropane carboxylic acid ester represented by the formula (V): ##STR13## wherein R represents C₁ -C₄ alkyl group or C₁ -C₄ alkyl group having halogen atom substituent, which does not indicate the configuration, to react with microorganisms selected from

Arthrobacter globiformis IFO-12958;

Thermomyces lanuginosus IFO-9863;

Rhodotorula rubra IFO-0918;

IFO-1100, IFO-0889, IFO-0909;

Candida humicola IFO-0760;

Candida lipolytica NRRL-Y-6795;

Aspergillus oryzae ATCC-14605;

Aspergillus flavus ATTC-11492; and

Bacillus sp. DC-1 (BP-FERM 1254)

or esterase produced by the above microorganisms until asymmetric hydrolysis is effected to produce (+)-trans-2,2-dimethyl-3(2,2-dichlorovinyl)cyclopropane carboxylic acid and diastereomer thereof and then recovering the resulting (+)-trans-2,2-dimethyl-3(2,2-dichlorovinyl)cyclopropane carboxylic acid or its salts.

The esters represented by the formula (II), which are starting materials in this invention, are easily obtained by well-known methods, for example, Pestic. Sci. Vol. 11, pp. 156-164 (1980). As the esters used as the starting materials, methyl ester, ethyl ester, propyl ester, butyl ester, monochloroethyl ester, monochloropropyl ester, monobromoethyl ester, etc. are conveniently used. Especially, methyl ester, ethyl ester, and monochloroethyl ester are advantageous because of commercial availability and ease in handling.

Example of salts of cyclopropane carboxylic acids represented by the formula (I) is alkali metal salt such as sodium salt.

Cultivation of the microorganisms is carried out in the usual procedure. For example, microorganisms are cultured in a liquid medium, for instance, inoculating microorganisms in a sterilized liquid medium and then cultivating usually at 20°-40° C., for 1-8 days with shaking. Alternatively, a solid medium may be used.

Any composition of the culture medium may be used, as long as the medium is familiar to cultivation of microorganisms and is utilizable by the microorganism used in this invention. As carbon sources and nitrogen sources in the medium, for example, glucose, starch, dextrin, molasses, fats and fatty oils, soybean powder, defatted soybean powder, fatty bean cake and corn steep liquor are employed. Ammonium sulfate, dipotassium hydrogenphosphate, magnesium sulfate and urea etc. may be used as inorganic salts in the medium. The cyclopropane carboxylic acid esters represented by the formula (II) or a fatty acid ester may be added to the medium. PG,14

In the method of this invention, asymmetric hydrolysis of cyclopropane carboxylic acid esters represented by the formula (II) is performed by mixing the esters (II) with a culture solution of the above microorganisms, a cell suspension, an esterase-containing aqueous solution such as a liquid esterase extract or its concentrated solution or their processed products, such as crude esterase, purified esterase etc., and then stirring or shaking the thus prepared mixture.

It is advantageous to perform the reaction at 10°-65° C. Since the stability of the esterase is likely to decrease at high temperature and the reaction rate is small at low temperatures, it is preferable that the reaction temperature be within the range of 20°-50° C. It is desirable that the pH of the mixture during reaction be 3-11, preferably around 5-10. It is preferable that buffers, such as phosphate buffer, be used to keep suitable pH during reaction.

Reaction time, which varies depending on the reaction conditions such as amount of esterase produced by the microorganisms, temperature during reaction, etc, is within the range of 2-3 to about 150 hours.

It is advantageous that the concentration of cyclopropane carboxylic acid esters represented by the formula (II) as a substrate when asymmetric hydrolysis is effected be 0.1-50 wt %, preferably 1-25 wt % based on a reaction liquid.

To the reaction mixture., 0.01-1% of surface active agents such as Triton X-100, Tween 80 or Brij 58 may be added, if necessary.

Cells of the microorganisms or the esterases may be used in the immobilized form, which is prepared by immobilizing them in a usual manner on inorganic or organic carriers, for example, zeolite, alumina, polysaccharide, polyamide, polystyrene resin, polyacrylic resin, and polyurethane resin, etc.

Cell suspension, suspension of ground cells or aqueous solution containing esterase, are prepared according to the usual method. Cell suspension is prepared by separating the cells harvested from culture medium by centrifugation or ultra filtration and suspending the cells in distilled water, ion-exchanged water, or buffer solution containing inorganic or organic salts, such as phosphate buffer solution. Suspension of ground cells is prepared by applying ultrasonic treatment, high pressure-breaking treatment by Manton-Gaulinhomogenizer or French Press or lytic enzyme treatment to the cell suspension. If necessary, the suspension may be changed to crude esterase solution by removing ground cell residue from the above suspension using centrifugation or ultrafiltration. Esterase is obtained from the suspension of ground cells by a conventional method, such as salting out with ammonium sulfate or sodium sulfate, or precipitation with organic solvents using hydrophilic organic solvents such as ethanol, propylalcohol, acetone, etc. Aqueous solution containing esterase is prepared by dissolving this obtained esterase in distilled water, ion-exchanged water, or buffer containing inorganic or organic salts, for example, phosphate buffer solution.

After the asymmetric hydrolysis is over, the liberated optically active cyclopropane carboxylic acid derivative represented by the formula (I) is separated from the unaltered ester and recovered by extraction with a solvent, column chromatography and fractional distillation, etc. For example, the reaction mixture is subjected to extraction with an organic solvent such as methyl isobutyl ketone, chloroform, ether, benzene or toluene and then the extract is subjected to fractional distillation under reduced pressure to separate the liberated optically active cyclopropane carboxylic acid derivatives represented by the formula (I) from the unaltered esters.

In view of the above facts, the present inventors have recognized the strain to be a novel one belonging to genus Bacillus and nominated it Bacillus sp. DC-1. The strain was deposited with Fermentation Research Institute, Industrial Technology Agency, Japan (Address: 1-3, Higashi 1-chome, Yatabe-cho, Tukuba-Gun, Ibaragi, JAPAN) under FERM BP-1254. The strain was first deposited as FERM P-8719 on Mar. 31, 1986, then renumbered as FERM BP-1254 under Budapest Treaty on Jan. 12, 1987.

This invention will be explained more precisely according to the following examples. However, this invention is not restricted to these examples and usual modifications or improvements of these are within the scope of the present invention.

EXAMPLES 1-23

First, 100 ml each of the following liquid media was put in a 500 ml flask and sterilized: a malt-extract-yeast-extract medium (pH 6.5, prepared by dissolving 5.0 g of peptone, 10.0 g of glucose, 3.0 g of malt extract and 3.0 g of yeast extract in 1 l of water) for yeasts and fungi (examples 1-7 and 15-21,); a sugar broth medium (pH 7.2, prepared by dissolving 10.0 g of glucose, 5.0 g of peptone, 5.0 g of meat extract and 3.0 g of sodium chloride in 1 l of water) for bacteria and actinomycetes (examples 8-14, and 22-23). A loopful of cells of each microorganism shown in Table 1 growing on slant culture was inoculated in the medium and the mixture was subjected to shaking culture at 30° C. for 20 hours.

1.0 g of ethyl (±)-cis-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylate of formula (II), in which X represents chlorine atom and R represents ethyl group, was added to the medium above and the mixture was allowed to react with shaking at 30° C. for 40 hours. After the reaction was over, the pH of the reaction mixture was adjusted to 2 or lower with concentrated hydrochloric acid and the mixture was subjected to extraction with methyl isobutyl ketone. Next, an internal standard (dimethyl phthalate) was added to the extract and the mixture was analyzed by gas chromatography (column: 3% Thermon 3000, 1.1 m, 140° C.). Then, the yield of 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylic acid [in formula (I), X is Cl and R is H] and the recovery rate of the ethyl 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylate used as the starting material were calculated by comparing their peak areas with that of dimethyl phthalate. It was found that all of the remaining ethyl 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylate which was not converted to 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylic acid was recovered. After that, the extract was mixed with IN sodium hydroxide solution to extract 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylic acid as sodium salt into the aqueous layer. Next, the pH of the aqueous layer was adjusted to 2 or lower with HCl solution to liberate 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylic acid which was then extracted by using methyl isobutyl ketone. After that, the extract was concentrated and evaporated to dryness to obtain substatially pure 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylic acid.

After 10 mg of thus produced 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylic acid was dissolved in 1 ml of toluene, equal molar amount each of thionyl chloride, pyridine and (+)-2-octanol were added and the mixture was allowed to react to produce diastereomers of ester of (+)-2-octanol and 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylic acid. Optical isomers assay in the diastereomers was performed by gas chromatography (column: 10% DCQF-1, 5.1 m, 180° C.).

The results are shown in the Table 10 in which the yield of 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylic acid represents the molar yield of 2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylic acid relative to ethyl (+)-cis-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylate contained in ethyl (±)-cis-2,2-dimethyl-3-(2,2-dichlorovinyl)cyclopropane carboxylate used as the starting material.

EXAMPLES 24-27

The same reaction and analysis as used in Examples 1-23 were performed except that 1.0 g of ethyl (±)-cis-2,2-dimethyl-3-(2,2-dimethylvinyl)cyclopropane carboxylate represented by the formula (II) wherein X represents methyl group and R represents ethyl group, was used as a substrate.

As a result, (+)-cis-2,2-dimethyl-3-(2,2-dimethylvinyl)cyclopropane carboxylic acid represented by the formula (I) wherein X represents methyl group and R represents hydrogen atom, was obtained. The results are shown in the Table 11.

EXAMPLES 28-31

The same reaction and analysis as used in Example 1-23 were performed except that 1.0 g of methyl (±)-cis-2,2-dimethyl-3-(2,2-dibromovinyl)cyclopropane carboxylate represented by the formula (II) wherein X represents bromine atom and R represents methyl group, was used as a substrate to obtain (+)-cis-2,2-dimethyl-3-(2,2-dibromovinyl)cyclopropane carboxylic acid [in the formula (I), X is bromine atom and R is hydrogen atom]. The results are shown in the Table 12.

EXAMPLE 32

After 30 g of soluble starch, 7 g of polypeptone, 5 g of yeast extract and 5 g of potassium dihydrogenphosphate were dissolved in 1 l of distilled water, the pH of the solution was adjusted to 5.0 with 6N hydrochloric acid. After 10 ml of the above liquid medium was put in a test tube of 24 mm diameter and pluged with cotton, it was sterilized at 120° C. under high pressure for 15 minutes. A loopful of cell of Arthrobacter globiformis IFO-12958 was inoculated to the medium and subjected to shaking culture at 30° C. for 24 hours, which was used as seed culture. After 300 ml of a liquid medium having the same composition as above was put in a 2 l Sakaguchi's flask and sterilized in the same manner as above, 5 ml of the seed culture prepared as above was inoculated to the sterilized liquid medium and was subjected to shaking culture at 30° C. for 30 hours. After that, the resulting culture was centrifuged to harvest 5 g (wet weight) of cells. The cells were suspended in 20 ml of 0.3M NaOH-Na₂ CO₃ buffer solution (pH 10) and then 0.1 g of ethyl (±)-cis-2,2-dimethyl-3-(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylate was added thereto. The mixture was allowed to react with stirring at 50° C. for 118 hours. Two ml of 35% hydrochloric acid was added to the reaction solution and the resulting mixture was applied to extraction with 50 ml of methyl isobutyl ketone. The extract was then analyzed by gas chromatography (column: Shinchrom F-51 (5%)+H₃ PO₄ (1%), 2.6 m, 185° C.) and the yield of cis-2,2-dimethyl-3-(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylic acid was calculated from the ratio of the peak area of this compound to that of ethyl cis-2,2-dimethyl-3(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylate. All of the starting ethyl cis-2,2-dimethyl-3(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylate were recovered in the form as it was excluding that which had been converted to cis-2,2-dimethyl-3(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylic acid. To the extract was added IN sodium hydroxide solution to produce a sodium salt of cis-2,2-dimethyl-3(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylic acid and then this salt was extracted into an aqueous layer. The pH of the aqueous layer was adjusted with HCl solution to 2 or lower to liberate cis-2,2-dimethyl-3(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylic acid and this compound was extracted with methyl isobutyl ketone. The extract was concentrated to obtain almost pure cis-2,2-dimethyl-3(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylic acid.

After 5 mg of the above cis-2,2-dimethyl-3(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylic acid was dissolved in 1 ml of toluene, equal molar amount each of thionyl chloride, pyridine and 3,5-dichloroaniline were added and the mixture was allowed to react to produce an anilide, which was subjected to analysis for optical isomers by high performance liquid chromatography (column: SUMIPAX OA-2100, moving phase: n-hexane/dichloroethane=17/3, flow rate: 1.0 ml/minute). The results are shown in the following table. The hydrolysis rate shown in the table represents the molar ratio of the resulting cis-2,2-dimethyl-3(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylic acid to ethyl (±)-cis-2,2-dimethyl-3(2-chloro-3,3,3-trifluoropropenyl)cyclopropane carboxylate used as the starting material.
